[H]ard|OCP got their hands on a very impressive kilowatt class PSU from Seasonic, the Platinum-1000. In their testing it did come incredibly close to the results at 80Plus, backing up the claim that this PSU deserves 80+ Platinum. As well, the hybrid fan design ensures near silent performance though [H] were hard pressed to hear the unit even when the fan was running full blast. The power provided was rock solid with barely a trace of ripple or noise on the lines. By the end [H] decrees that "The Seasonic Platinum-1000 is quite literally THE power supply on the market today."

"Seasonic breaks the Platinum efficiency barrier with its new 1 kilowatt computer power supply. We generally know if it has Seasonic branding, it is a good PSU. But we all want to know if it is a great PSU. We all know that Seasonic means "quiet" as well and believe it or not this PSU can be dead silent."
